Tiny-yolo v3 FPS not same as benchmarked on Jetpack 4.6

Hi, i recently installed Jetpack 4.6 and trying to benchmark yolov3-tiny using jetson_benchmarks.

I’m getting half the FPS (21) in place of 45, what might be the issue?

clutterbot@jetson:~/infer/jetson_benchmarks$ sudo python3 benchmark.py --model_name tiny-yolov3 --csv_file_path /home/clutterbot/infer/jetson_benchmarks/benchmark_csv/tx2-nano-benchmarks.csv --model_dir /home/clutterbot/infer/jetson_benchmarks/models/ --jetson_devkit nano --gpu_freq 921600000 --power_mode 0 --precision fp16

Hi,

Thanks for reporting this issue to us.

We are double-checking the performance on JetPack 4.6.
Will get back to you later.

Thanks.

Hi,

We verify this internally with JetPack 4.6 on Nano and can get 46fps without performance regression.
Could you try it again?
